Supersymmetric quiver gauge theories: a phenomenological perspective
The recent LHC discovery of a Higgs-like particle that could be involved in electroweak symmetry breaking places strong bounds on the parameter space of supersymmetric models. In particular, it has been argued that minimal gauge mediated supersymmetry breaking scenarios seem to be at odds with a Higgs boson of ~126 GeV. Supersymmetric quiver gauge theories are an already well-established attractive class of models, communicating SUSY breaking to the visible sector via linking fields. These models arise naturally in high-energy models, and interpolate between general gauge and gaugino mediated supersymmetry breaking. Recently, it has been shown that they can fairly easily accommodate a Higgs boson of ~126 GeV. In this talk, we will explore phenomenological aspects of SUSY quiver models relevant both for colliders and dark matter searches.
